Hi Emily,
Glad to hear you are considering the Bay Area. It’s beautiful up here!
Some firms to look at in Marin County (North of SF) are:
April Philips Design Works
SWA – Sausalito
Blasen Landscape Architects
RHAA
Shades of Green
Blasen was just looking for an entry level candidate, so they might be a good place to start. Although, everyone is very slow right
now. I would recommend approaching each firm for an informational interview/ office visit. Most firms like to show off their office plus they have more time to spend with you because of the slow times. It is a great (and easy) way to get your foot in the door.
Good luck!
